Abstract

Abstract A universal stretcher rail system for use in connection with a space dividing wall panel system including wall panels of different lengths having vertically oriented, laterally spaced slotted standards at each end thereof. The system includes an inner rail member and a plurality of outer rail members of varying lengths each individually adapted to be selectively telescopically associated with the inner rail member to produce a stretcher rail of more than one predetermined length. L-shaped support brackets are fixed to the remote ends of the inner and outer rail members to interconnect the stretcher rail to a pair of laterally spaced slotted standards.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 140 words
A wall hung, telescoping stretcher rail for use in connection with a free standing, space dividing, wall panel system having laterally spaced vertical slotted standards, said stretcher rail comprising: an inner rail member; a hollow tubular outer rail member adapted to telescopically receive said inner rail member; a first L-shaped mounting clip secured along one leg thereof to the outer surface of said inner rail member adjacent one end thereof; a second L-shaped mounting clip secured along one leg thereof to an inner surface of said outer rail member adjacent one end thereof; and connector means at the ends of the other legs of each of said first and second mounting clips extending away from said rail members, said connector means constructed and arranged to coact with said vertical slotted standards to mount said stretcher rail to said wall panel.
Claim 2
Dependent Claim 140 words
A wall hung, telescoping stretcher rail for use in connection with a free standing, space dividing, wall panel system having laterally spaced vertical slotted standards, said stretcher rail comprising: an inner rail member; a hollow tubular outer rail member adapted to telescopically receive said inner rail member; a first L-shaped mounting clip secured along one leg thereof to the outer surface of said inner rail member adjacent one end thereof; a second L-shaped mounting clip secured along one leg thereof to an inner surface of said outer rail member adjacent one end thereof; and connector means at the ends of the other legs of each of said first and second mounting clips extending away from said rail members, said connector means constructed and arranged to coact with said vertical slotted standards to mount said stretcher rail to said wall panel.
Claim 3
Dependent Claim 69 words
The wall hung telescoping stretcher rail according to claim 1 wherein each of said inner and outer rail members are rectangular and said outer rail member includes a plurality of key slots in the upper and lower surfaces thereof, said inner rail member including a plurality of depressions in the upper and lower surfaces thereof constructed and arranged to align with said key slots in said outer rail member.
Claim 4
Dependent Claim 171 words
A universal stretcher rail system for use in connection with a space dividing wall panel system including wall panels of different lengths having vertically oriented laterally spaced slotted standards at each end thereof, said stretcher rail system comprising: an inner rail member; a plurality of hollow tubular outer rail members of varying lengths each individually adapted to be selectively associated with said inner rail member to produce a stretcher rail of a predetermined length, said inner rail member being telescopically received in said outer rail member; a first L-shaped mounting clip secured along one leg thereof to the outer surface of said inner rail member; a second L-shaped mounting clip secured along one leg thereof to an inner surface of said outer rail member; and connector means at the ends of the other legs of each of said first and second mounting clips extending away from said rail members, said connector means constructed and arranged to coact with said vertical slotted standard to mount said stretcher rail to said wall panel.
Claim 5
Dependent Claim 171 words
A universal stretcher rail system for use in connection with a space dividing wall panel system including wall panels of different lengths having vertically oriented laterally spaced slotted standards at each end thereof, said stretcher rail system comprising: an inner rail member; a plurality of hollow tubular outer rail members of varying lengths each individually adapted to be selectively associated with said inner rail member to produce a stretcher rail of a predetermined length, said inner rail member being telescopically received in said outer rail member; a first L-shaped mounting clip secured along one leg thereof to the outer surface of said inner rail member; a second L-shaped mounting clip secured along one leg thereof to an inner surface of said outer rail member; and connector means at the ends of the other legs of each of said first and second mounting clips extending away from said rail members, said connector means constructed and arranged to coact with said vertical slotted standard to mount said stretcher rail to said wall panel.
Claim 6
Dependent Claim 67 words
The universal stretcher rail system of claim 3 wherein each of said inner and outer rail members are rectangular and said outer rail members include a plurality of key slots in the upper and lower surfaces thereof, said inner rail member including a plurality of depressions in the upper and lower surfaces thereof constructed and arranged to align with said key slots in said outer rail members.
